1. In a mixture of 60 litres, the ratio of milk and water is2:3. How much water must be added to this mixtureso that the ratio of milk and water becomes 1:2?(a) 10 litres(b) 12 litres(c) 15 litres(d) 20 litres

Answer»

Answer:

12 litres

Step-by-step explanation:

$\pmb{ \sf Given : - }$

In a MIXTURE of 60 litres, the RATIO of MILK and water is 2:3.

$\pmb{ \sf \: To \: Find : - }$

Water must be added to this mixture so that the ratio of milk and water becomes 1:2.

$\pmb{ \sf \: Solution:-}$

$\sf \: Given \: ratio = 2 : 3 \\ \\ \leadsto \: \sf Sum \: of \: ratios = 2 + 3 \\ \leadsto \sf \: \purple 5$

$\sf \: Quantity \: of \: milk = \frac{2}{ \cancel5} \times \cancel{ 60} \\ \leadsto \sf \: 2 \times 12 \\ \leadsto \bf \purple{24 \: l}$

$\sf \: Quantity \: of \: water = 60 - 24 \\ \dashrightarrow \bf \purple{36 \: l}$

Now,

$\bigstar \rm \: \: Let \pink{ \bf \: x l} \: be \: added$

ACQ,

$\therefore \tt \: \frac{24}{36 + x} = \frac{1}{2} \\ \longrightarrow \tt \: 1(36 + x) = 2(24) \\ \longrightarrow \tt \: 36 + x = 48 \\ \longrightarrow \tt \: x = 48 - 36 \\ \longrightarrow \tt \: \bf \color{aqua} \: x = 12 \: l$

So,

Sides of triangle are 70 cm ,80cm,90cm find the area and length of the shortest altitude (use root 5=2.23

Answer»

Answer:

A= 70 cm

B= 80 cm

C= 90 cm

Semi-perimetre = (70+80+90)/2

= 240/2

= 120 cm

Area of ∆ = √{120(120-70)(120-80)(120-90)}

Answer» Step-by-step explanation: first simplify these eqns by dividing by 4 and 3 respectively we get 4x+3y=14 1 and 3x+4Y=21 2 *here* *for* *eliminating* *any* *VARIABLE* *take* *the* *value* of *that* *variable* *from* *one* *eqn* *and* *put* it *into* 2nd *eqn* we *will* *get* *the* *result* by 1st eqn we get X=(14-3y)/4 on substituting this in 2nd eqn [3(14-3y)/4] + 4y= 21 on multiplying the eqn by 4 we get 42-9y+16y=84 y=6 now we know the value of x in TERMS of y so we substitute value of y in that expression x=-1 if you CANT understand even after this please try yourself you will definately get the clarity

16x +12y =56 and 9x+12y =69 elimination method

Answer»

Step-by-step explanation:

first simplify these eqns by dividing by 4 and 3 respectively

we get 4x+3y=14 1

and 3x+4Y=21 2

here for eliminating any VARIABLE take the value of that variable from one eqn and put it into 2nd eqn

we will get the result

by 1st eqn we get X=(14-3y)/4

on substituting this in 2nd eqn

[3(14-3y)/4] + 4y= 21

on multiplying the eqn by 4

we get 42-9y+16y=84

y=6

now we know the value of x in TERMS of y

so we substitute value of y in that expression

x=-1

if you CANT understand even after this please try yourself

you will definately get the clarity

Find the rational number between 5/3 and 6/3

Sides of triangle are 70 cm ,80cm,90cm find the area and length of the shortest altitude (use root 5=2.23

Answer:

A= 70 cm

B= 80 cm

C= 90 cm

Semi-perimetre = (70+80+90)/2

= 240/2

= 120 cm

Area of ∆ = √{120(120-70)(120-80)(120-90)}

= √{120×50×40×30}

= √{4×3×10×5×10×3×10×4×10}

= 4×3×100√5

= 1200× 2.23

= 1200× 223/100

= 2676cm^2

THEREFORE, Area of ∆ is 2676cm^2
